Benefits of technology

"The present invention is a switching device that controls the communication between electronic and input devices. When the switching device is activated, the electronic and input devices are in communication with each other, and a digital control signal is allowed to flow between them. This allows for the control of the electronic device by the input device. When the switching device is deactivated, the electronic and input devices are not in communication with each other, and the digital control signal is not allowed to flow between them. This provides security to the electronic device by controlling the communication between it and the input device."

Problems solved by technology

When the switching device is deactivated, the electronic and input devices are not in communication with each other, and the digital control signal is not allowed to flow between them.
The operation of the electronic device cannot be controlled by the input device unless the digital control signal is received by the electronic device.

Embodiment Construction

[0016]FIG. 1 is a block diagram of an electronic system 100, in accordance with the invention. In this embodiment, electronic system 100 includes a switching device 103 connected between an input device 102 and an electronic device 101. In accordance with the invention, switching device 103 allows and disallows, in response to a security signal SSecurity, input device 102 to communicate with electronic device 101. Input device 102 can control the operation of electronic device 101 when input device 102 is allowed to communicate with electronic device 101. Further, input device 102 cannot control the operation of electronic device 101 when input device 102 is not allowed to communicate with electronic device 101.

[0017]Switching device 103 can be of many different types, such as a relay, key switch and filter. There are many different types of relays that can be used, such as those made by Zettler Automotive of Aliso Viejo, Calif. Further, there are many different types of filters tha...

Abstract

An electronic system includes an input device and an electronic device, and a switching device connected between them. The switching device allows and disallows access of the input device to the electronic device in response to a security signal. The input device is connected to the electronic device when the switching device is activated. The input device is disconnected from the electronic device when the switching device is deactivated.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to an electronics system with restricted access.[0003]2. Description of the Related Art[0004]It is often desirable to provide security to an electronic system by restricting access to it. By restricting access to the electronic system, its unauthorized use is prevented. Restricted access to the electronic system can be provided in many different ways. For example, the electronic system often includes a controller in communication with an input device. Access is provided to the controller in response to a predetermined access input signal being provided to the controller through the input device.[0005]There are many different ways the predetermined access input signal can be provided to the controller. For example, the input device can be a computer system operating security software. The predetermined access input signal is then provided to the security software as a username and password. The inp...
